Odd Desync problem.

[warlord1616]

Hello. I have no trouble playing multiplayer with all of my friends but one. He's brand new to the game, so I'm writing this for both of us. Here's what happens: I'm hosting a game, we both select our empires, we ready up, we get into the game, I click the "paused" button to start it right away, and it gets maybe to day 1-2 and it desyncs.

Now, I know it's not a matter of actions queued while paused, so don't suggest that being the problem please. Resyncing won't help for more then 15 days before it happens again.

I'm stumped, please help.

Anyone?

Using Stellar Stellaris mod any of you?
Known to cause desync in the latest patches (still work rock solid in single player)

If no mods involved (aka you playing vanilla) then desync can be caused by a variety of factors.
Mostly network latency that causes packet loss. If you or your friend internet connection has a suboptimal latency, desync is very common. This is most likely on the player that host the game.

Another cause can be third party software, background applications like firewall or AV , can interfere with the communication, but this is less likely, still something to keep in mind, try to whitelist the game on both you and your friend AV/Firewall.

Also worth for both of you to verify game files integrity to make sure no one of you has corrupted files.

Not using mods. I'll ask him about the other factors.

Check the time difference between client & host. Can be viewed at the top right in the galaxy time. Excessive differences can trigger desyncs.

Usually happens when the hardware performance of client & host are too far apart. (for example, a 7800x3d vs 3700x CPU)

This can be prevented by the player with the weakest hardware hosting the game.

Or by setting the ingame time to very slow. (But it can still happen that the hardware performance is still too far apart).

It said the same day. It was always right upon game start.

If this only happens once, save the game and host a new lobby.

And you can try changing the host.

If this happens more often, then well, I don't know. There are lots of forum posts, some of which have been happening for years. The cause is unclear.
